> NM does not reference the singleton JvmMetrics instance in its
> NodeManagerMetrics. This will easily cause NM to crash if any of the node
> manager components tries to register JvmMetrics. An example of this is
> TimelineCollectorManager that hosts a HBaseClient that registers JvmMetrics
> again. See HBASE-19409 for details.
